Common Heat Treatment Methods For Molds

Mold heat treatment is mainly for steel molds, so the mold heat treatment process refers to the specific heat treatment heating, heat preservation and cooling process parameters that are formulated according to the rules of organizational transformation during the heating and cooling of the mold steel.

According to the different heating and cooling methods and the obtained structure and performance, the heat treatment process can be divided into conventional heat treatment and surface heat treatment. The conventional heat treatment of die steel mainly includes annealing, normalizing, quenching and tempering.
Mold heat treatment is one of the key processes in mold manufacturing, which is directly related to mold manufacturing accuracy, mechanical properties (such as strength, etc.), service life, and manufacturing cost, and is an important link to ensure mold quality and service life. The correct selection of steel and a reasonable heat treatment process will play a major role in giving full play to the potential performance of the material, reducing energy consumption, reducing costs, and improving the quality and service life of the mold.

The current rapid development of mold heat treatment technology is vacuum heat treatment technology and mold surface strengthening technology. According to the position and role of heat treatment in the production process of parts, mold heat treatment can be divided into preliminary heat treatment and final heat treatment.
